Posterior chamber phakic intraocular lens implantation for high myopia / 中华医学杂志(英文版)

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the efficacy, safety and stability of posterior chamber phakic intraocular lens (PIOLs) implantation for the correction of high myopia.</p><p><b>METHODS</b>Thirty-nine eyes of twenty patients with high myopia (between -11.75 and -25.75 diopters) had a posterior chamber PIOL (Staar ICL) implanted. During 6 - 48 months' follow-up, visual acuity, refraction, intraocular pressure (IOP), corneal reaction and space between crystal lens and intraocular lens (IOLs) were tested.</p><p><b>RESULTS</b>Successful implantation was achieved in all patients. Visual acuity without correction greater than 0.5 was found in 34 eyes at 1 day and 3 months postoperatively. Thirty-five eyes maintained a low negative power of refraction (-1.42 +/- 1.32 doipters), which did not prevent the patients from most of their daily activities. During 3 - 48 months' follow-up, refraction was stable and no cornea edema and glaucoma was found. Two eyes of one patient had corticosteroid glaucoma and another eye showed cataractogenesis under anterior capsular membrane.</p><p><b>CONCLUSION</b>Posterior chamber PIOL implantation is predictable, safe, and effective in the correction of high myopia, and its indications should be carefully selected.</p>
